    • A medial-axis-based model for propagating cracks in a regularised bulk 

      Tamayo Mas, Elena; Rodríguez Ferran, Antonio (John Wiley & Sons, 2015-02-17)
      Article
      Accés obert
      A new continuous-discontinuous strategy for the simulation of failure is presented. The continuous bulk is regularised by means of a gradient-enhanced damage model, where non-locality is introduced at the level of ...

    • A permafrost test on intact gneiss rock 

      Duca, S; Alonso Pérez de Agreda, Eduardo; Scavia, Claudio (Elsevier, 2015-07)
      Article
      Accés obert
      Changes in permafrost conditions in high mountain rocks have increased the risk of dangerous instabilities. Ice segregation within the rock mass has been interpreted as one of the mechanisms involved in high mountain bedrock ...

    • Cell-based maximum-entropy approximants 

      Millán, Daniel; Sukumar, N; Arroyo Balaguer, Marino (2015-02-01)
      Article
      Accés obert
      In this paper, we devise cell-based maximum-entropy (max-ent) basis functions that are used in a Galerkin method for the solution of partial differential equations. The motivation behind this work is the construction of ...

    • Efficient implementation of Galerkin meshfree methods for large-scale problems with an emphasis on maximum entropy approximants 

      Peco, Christian; Milian, Daniel; Rosolen, Adrian Martin; Arroyo Balaguer, Marino (2015-04-01)
      Article
      Accés obert
      In Galerkin meshfree methods, because of a denser and unstructured connectivity, the creation and assembly of sparse matrices is expensive. Additionally, the cost of computing basis functions can be significant in problems ...

    • Material flow visualization in Friction Stir Welding via particle tracing 

      Dialami Shabandarech, Narges; Chiumenti, Michele; Cervera Ruiz, Miguel; Agelet de Saracibar Bosch, Carlos; Ponthot, Jean Philippe (2015-04)
      Article
      Accés obert
      This work deals with the modeling of the material flow in Friction Stir Welding (FSW) processes using particle tracing method. For the computation of particle trajectories, three accurate and computationally efficient ...
